CONTROLLING DEVICE FOR WINDING-MACHINES' Application filed June 29, 1912.

. --trolling winding machines, whereby uniform lengths of thread may be wound upon holders, such as spools or tubes. In my Patent No. 1,030,147 dated June 18, 1912, I have shown a device of this character" in which the winding operation is stopped by a mechanically controlled mechanism.

One feature of the present invention contemplates the provision of electro-responsive means for controlling the winding operation when a predetermined weight of thread has been wound upon the holder.

A further feature contemplates the provision of means for automatically severing the thread when the predetermined amount of thread is wound upon the holder. The winding operation may be stopped without severing the thread, or the thread may be severed without stopping the machine when a full length has been wound, or the device may be arranged to sever the thread and stop the machine simultaneously.

The invention will be clearly understood from an inspection of the accompanying drawing, in whichvFigure 1 is a fragmentary front elevation showing one embodlment of the invention applied to a so-called Universal winding machine, Fig. 2 is a sideelevatlon of the same, Fig. 3 is a perspective detail view of the contaotarm and knife, Fig. 4 is a side elevation, partly diagrammatic, of a-modified form of the invention, and Fig. 5 is a fragmentary side elevation showing a thread guide.

The present embodiment of the invention is shown applied to the well known Universal winding machine, which is illustrated and described in the patent granted to S. W. Wardwell, No. 801,941 dated October 17 1905, but it should be understood that the invention is readily applicable to other styles of winding machines.

As illustratedin Figs. 1 to 3, inclusive, the winding machine comprises a frame 10, having a winding spindle 12, driven by a pulley 14, the latter being shown in Fig. 4 only. A thread holder 16, whlch may be a Specification of Letters Patent.

Serial No. 706,623.

tube or a spool, is held on the winding spindle by a nut 17 and upon this holder the mass of thread 18 is wound from the supply. The supply of thread may be supported in various ways, for example, in this form of the device it is intended to be supported in the manner shown in my said patent. The thread passes from the supply to a tension device 20, thence under a finger 22 on a wire lever 24, the latter being fulcrumed at 25 on a sector 26 of a stop-motion device carried by a swinging traverse frame 28. The sector is fulcrumed at 27 on the main frame 10. The lever 24 is formed with a leg 30 composed of wire, the innerend of which hangs adjacent to the corrugated rim of a wheel or disk 32 carried by a cam shaft 34 and rotating in the direction of the arrow. From the finger 22 the thread passes to a reciprocating guide 23. Whenever the thread breaks, the finger 22 is unsupported and the lever tilts so that the loop or leg 30 engages the rim of the wheel 32, whereupon the stop-motion is actuated as explained in the patent to Wardwell above mentioned;

My device is adapted to be applied bodily to the above described winding machine without changing any of its instrumentalities above set forth. In order to accurately control the stopping of the winding operation when a predetermined amount of thread is wound on the holder, I provide means for holding a supply of thread which is arranged to be balanced. The balancing device may be such as is shown in my said patent, in which'a plurality of like, net thread weights and adjustable weights are arranged to balance the supply. A rod 40, similar to the rod 48 of my said patent, is adapted to support the thread from which a holder is filled. This rod depends from the balancing device, as shown in my said patent, and is provided with an arm 42 insulated therefrom by a bushing 48, and having a contact 44 at its" free end. A conductor 46 connects the contact 44 with one pole of a battery 47, and the other pole of the battery is connected by a conductor 48 to one terminal of an electromagnet 50. The other terminal of the electromagnet is connected by a conductor 52 to a stationary contact 53, mounted on, but insulated from, the

frame 10. An armature 54 for the electro magnetis mounted on the sector 26, said magnet being supported by a bracket 55 the bar 56 is raised into contact with the thread. The vibrating thread isthus caught in the notch 57 and drawn against one of the aflixed to the frame 10. In this formof the device the winding operation is commenced by removing one of the net thread weights, as explained in my said patent, whereupon the rod 40 is lowered and the contacts 4st and 53 are separated. If the thread breaks, the stop-motion is actuated as explainedin' the above mentioned patent to Wardwell- V7 hen the required amount of thread is wound upon the holder 16, the balanceis'restored and the rod lO rises to bring the con-' tacts 4:4 and 53 into engagement. Tl1e c1r-.

cuit through the electromagnet 50- is thus closed and the latter is thereby energized;

The electromagnet attracts its armature'54 and thus swings the sector 26 about its'fulcrum 27 to actuate the stop-motion,-whereupon the winding operation is stopped;

. In some instances it may be desirable to automatically severthe thread whe'n the pre-: 7 determined amount has been wound upon the holder. To accomplish this a bar 56'is affixed to the rod 40 in proximity to' the finger 22 and provided with a dovetail'slot' 57 having its inclined edges 58 sharpened to form knives. During the winding operation the thread passes from the tension device in proximity to the upper edge of the bar 56, then under the finger 22, and through the reciprocatory guide23. When the balance is restored, by having the desired length of thread wound upon the holder 16,

knives 58 and severed, thus preventing the thread from being wound upon the holder.

- In Fig. 4: Ihave shown a modified form in which the balancing device 60 is mounted upon the floor, the supply of thread 61 be ing balanced bythe net thread weights 62 and the adjustable weights 63 and 64:- A

: stationary contact 66 is mounted on, but inconductor 74 with the movable contact 67.

The operation of this form of the device is obvious from the explanation given above.

'It obviates the necessity of the rod .40 and connected parts at the front of the machine.

' In Fig. 5 I have shown a modified form of thread guiding means adapted for use when the balancing device is mounted upon the top of the winding machine. It comprises a rod 80 aitlxed to a scale pan 81 and bent at right angles to form a horizontal arm 82,

the latter being provided with two threadguiding eyes or loops 88, 84. By using this am aware that many modifications can be" made therein by any person skilled: in theart Without departing from the scope .of the invention as expressed in the claims.
